From: Baochen Qiang <bqiang@xxxxxxxxxxxxxx>
The buffer pointed to by event is not freed in case
ATH11K_FLAG_UNREGISTERING bit is set, resulting in
memory leak, so fix it.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
